Welcome to this active site. Each week I am going to present to you an endgame position for you to solve or to workout the best continuation. Computer analysis will also be considered. Some of these positions will come from actual historical games. Others will be composed endgame studies, but all the solutions will be relevant to the practical game. The new position will occur each SUNDAY and I will always be pleased to receive POSITIVE feedback about the positions and the analysis and I will try to acknowledge these where relevant.

Thanks to Antonio Senatore, Henryk Kalafut, Federico Giallombardo, Jim Monaghan, Jon Palmer and Alexander Voyna.

White to Play and DRAW (?)

FORSYTH NOTATION

:1k3B1r/N7/7P/8/3n4/7K/1b6/8 w - - 0 1:

This study gained first prize in a study tourney in 1923 but many years later it was found to be unsound. The flaw was discovered by Ilya Maizelis in 1956, the world famous endgame expert, who had worked with Averbakh in the 1950s. He showed that by a remarkable piece of analysis Black could in fact win. Your editor had forgotten about this discovery until only a few days ago after a belated literature search. ( The Encyclopaedia of Chess by Anne Sunnucks. 1976 ) I apologize for any inconvenience caused. In the following analysis the composer's solution is given as the main line and Maizelis' refutation is shown in red. I hope you will agree with me that the flawed study is still a wonderful creation of art which only just fails.

 1.Bg7 Rh7!

The only place for the Rook which gives chances for a win.

1...Re8 2.Bxd4 Bxd4 3.Nc6+ Kb7 4.Nxd4=;

2.Kg4! ...

2.Bxd4? Rxh6+ 3.Kg4 Bxd4 Black wins;

2... Kxa7

It is ironic that Black can win by not capturing the Knight at this point. 2...Kb7!! 3.Kh5 Nf5 4.Kg6 (4.Bxb2 Rxh6+ 5.Kg5 Rb6! 6.Be5 Nd6 7.Bd4 Rb1 8.Kf6 Nc4 9.Ke6 Nb6 Black wins) 4...Nxg7 5.Kxh7 Ne8 Black wins because the enemy Knight is lost and his pieces can soon take care of the h-pawn. 6.Nb5 Kb6 7.Kg8 Kxb5 8.h7 Nf6+ 9.Kg7 Ng4+ 10.Kg8 Nh6+ and Black wins;

3.Kh5 Nf5

A year before the Maizelis analysis was published Grandmaster Bondarevsky tried to show that 3...Ne6 4.Bxb2 Rb7 5.Ba3 Rb3 wins for Black but he missed: 6.Kg4!! Nd8 7.h7 Nf7 8.Be7 Rb7 9.Bf6 Rb8 10.Kh5 =;

4.Bxb2 ...

4.Kg6? Rxg7+ 4.Kg6? Rxg7+ 5.hxg7 Nxg7 Black wins;

4...Rxh6+

A fascinating duel now starts in which the Bishop is equal to the Knight and Rook.

5.Kg5 Rh2

5...Rb6 6.Be5! Ne7 7.Bd4 =;

6.Be5 Rf2

7.Bf4! Nd4!

8.Be3 ...

The pin on the Knight brings Black's game to a standstill.

8... Rf5+

9.Kg4 Rd5

All these moves by Black are forced.

10.Kf4 Kb6

11.Ke4 Kc5

12.Kd3 DRAW

The Knight is pinned and the Rook and Bishop can move back and forth with no progress being made. It is a positional draw. If the Knight is given up a theoretical drawn ending of K+B vs K+R is reached.

 

Gens Una Sumas. 
Gerard O' Reilly wins in May.
